Directions: There are six steps that lead from the first to the second floor. No two people can be on the same step Mr. A is two steps below Mr. C Mr. B is a step next to Mr. D Only one step is vacant ( No one standing on that step )Denote the first step by step 1 and second step by step 2 etc. If Mr. A is on the first step, Which of the following is true?

If Mr. A is on step 1, then Mr. C must be on step 3 (since A is two steps below C). This leaves steps 2, 4, 5, and 6 for B and D, who must be on adjacent steps. The only way to satisfy the condition that A is on a higher step than D is if D is NOT on step 1 (already occupied by A). Therefore, D must be on a higher step than C (step 3), which means D could be on step 4, 5, or 6. Option D states D is on a higher step than C, which must be true since A occupies step 1 and C is on step 3.
